AI product recommendation popup after 15 seconds: +27% purchases
Test run byOptiMonkTesting and CRO tool
Commentary byLiftArchiveOur analysis, not theirsAdding an AI product-recommendation popup that appeared after 15 seconds of browsing lifted Gelpro Australia's ecommerce conversion rate (purchases) by 27%.
OptiMonk ran it for the collagen supplement brand and published it as a case study.
The case study does not say how the comparison was made.
- Ecommerce conversion rate (purchases): +27%.
- The case study headline frames the 27% as a desktop gain, while the body applies it to purchases overall, so the scope is unclear.
- Gelpro also ran a browsing reminder (+4%) and an exit-intent cart reminder (+6%) at the same time. Those are logged as separate results.
The change
The variant adds a timed popup recommending products related to the one being viewed.
Simplified mockup drawn by LiftArchive from the shared screenshots.
Control
No recommendation popup. Gelpro had been using Klaviyo popups for email capture.
Variant
A popup with AI product recommendations based on the item being viewed, shown only after 15 seconds of browsing and built to work on mobile.
Why it likely won
Our reading of the result, not the practitioner's claim.
- Waiting 15 seconds means the popup reaches people who are browsing, not those who just landed.
- Recommendations tied to the current product help shoppers find a better match in the range.
- Supplement buyers often need help choosing between similar products.
Caveats: The case study doesn't say whether this was a split test or a before-and-after comparison. Sample size and duration are not shared, other campaigns ran at the same time, and the result is vendor-reported.

How to run this test on your store
- Hypothesis
- If we show a product-recommendation popup based on the item being viewed after 15 seconds of browsing, then purchases will rise because shoppers find a product that fits without searching.
- Primary metric
- Ecommerce conversion rate
- Guardrails
- Bounce rate
- Average order value
- Mobile conversion rate
- Who should test it
- Health and supplement stores with a range of related products. If you sell one hero product, there is little to recommend and the popup may just distract.
Questions
How long should I wait before showing a recommendation popup?
Gelpro waited 15 seconds so the popup reached people already browsing.
Test a few delays, since the best timing depends on how long people usually stay.
Do AI product recommendations work for small stores?
They can if you have enough related products to suggest.
With a very small range, the recommendations repeat and add little.
